I'm creating a SPA developed in Angular2 with a backend server developed in Laravel.
Angular2 app plays video files stored in different cloud providers (Google drive, SMB server, Dropbox, OneDrive,...) but those providers are handled by Laravel API.
This is the application architecture:
Is there a way to serve a file stored in those providers without download the file in the Laravel server first?
Any help would be appreciated.
Thanks.
EDIT
Files are not publicly accessible. Authentication set up and working in Laravel backend.
I presume by "download", you want to avoid the delay while the entire file is fetched before the user sees the first video frames. The only approach I can think of is to chunk the downloads using standard http chunking between Laravel and Drive, and then echo that in the http session between your Angular app and Laravel. NB I haven't tested this, but I believe chunking is supported by Drive.
In general case a kind of proxy is unavoidable. You can pipe streams from the cloud to the stdout e.g. Stream FTP download to output or similar.
If a cloud support presigned urls, e.g. s3 http://docs.aws.amazon.com/AmazonS3/latest/dev/ShareObjectPreSignedURL.html you can benefit from web server redirects, like X-Accel-Redirect in nginx https://www.nginx.com/resources/wiki/start/topics/examples/xsendfile/.

I have project that needs to output hundreds of photos from one template file, compress them into a .zip file, and push them to the customer's browser. After that, the .zip file can be deleted.
Google App Engine (PHP) does not allow you to write files like you would in a standard web server.
How can this be accomplished with GAE flexible?
As you have already known, App Engine flexible does not allow you to write files on the system even if it runs on a VM. The reason is that it runs within more Docker containers and you will not have the guarantee that you will find the file.
An alternative for this is to change a bit your workflow and to use Cloud Storage as an intermediate. You can send the photos directly to Cloud Storage, and the users will be able to download them directly from Cloud Storage. Here you have a guide on how to achieve this from App Engine flex for PHP.
We have developed our application in Laravel and now we are planning to transfer it to Amazon server where we have to separate our application logic with file storage. Basically, we want to move our whole application storage to a cloud server(Amazon S3) and application logic to Amazon EC2 server.
In our system, we manipulate (resize images, merge images, make thumbnails from videos, etc) many storage files locally. We will not be going to store any files on the application server once we migrate to Amazon server. So, our concern is how we can manipulate cloud server files?
Earlier all files are present on the application server so file manipulation was easy to process but after migrating whole storage to cloud server how we can manipulate files that are on the cloud server with manipulation logic resides on the application server?
Any Response will be helpful
Thanks in advance...
To manipulate S3 file, I think first we need to download the file locally. Once, we have file locally we can apply any operation on that particular file. We can delete the local file later.
Here are the documents to directly upload from or download to a local file using the Amazon S3.

I use this code
move_uploaded_file($file_tmp,$us_id.".jpg");
but after run this script it not error but file not appear into folder ,how can it do?
before these, I test in localhost it work.
You haven't specified what $file_tmp contains, but... in an Azure Web App, the root folder is at d:\home\site\wwwroot. And you'll find the %HOME% environment variable set to d:\home.
Edited based on #David's comments and Kudu's Azure runtime environment
In a Cloud environment, saving files to the current filesystem of your Web App is not advised. If you simply upload your site through FTP, you might not have issues, but if you rely on Continuous Integration or automated deployment scenarios, your site folder might change or have content overwritten.
That is why, for storage of files that need to be accesed in the future or need to be permantently saved, you might want to use something like Azure Blob Storage. Not only is really cheap, but you can apply CDN over it for improving your files delivery.
Here is how to use it on PHP and the Azure SDK for PHP.
As I leverage your code at Azure window sever can't upload file from php in my test project, it works perfectly on my side, even I don't value the $us_id in your code, the picture is still updated to the uploadimg folder with the name .jpg.
I suspect whether if your Web Apps's disk space has reached the limitation of your App Service plan.
As every App Service pricing tier has a limit disk space and will shared in all the web apps in this App Service plan. You can check the metric on dashboard page of your web app portal, e.g.
You can refer to https://azure.microsoft.com/en-us/pricing/details/app-service/ for details.
If using Windows Azure and an ASP.NET web site with PHP script to upload files, can I access those files from the server or must I use the Data Storage facilities?
i.e. I'd like to reference the files directly from html\server... etc. I think I probably should be able to.
Thank you.
How are you hosting your ASP.NET website. If it's hosted in a Web Role, then you won't have access to a persistent "standard" file system for that role. (especially if you've scaled over multiple instances).
Have a look at the following tutorial on using blob storage from PHP. http://www.windowsazure.com/en-us/develop/php/how-to-guides/blob-service/
You can use the blob storage quite easily to access them with standard HTTP links from your ASP.NET site. i.e.
http://your-storage-account.blob.core.windows.net/your-container/file.txt
I want to develop a website like file manager. Where user register and will get fix disk space lets say 20MB.
Now user can upload their pdf, doc, txt, jpeg etc files upto their disk limit.
I can develop upto this using PHP.
Now below is my issue:
1) If user's files are corrupted they can rollback their folders before 2-3 days.
Files must be secure and safe from viruses as users are uploading their important documents.
Is there any 3rd party storage server who provides such facility?
2) Also all files should be previewed from browser.
I am using Google doc viewer. Is is good and safe way to preview file in browser?
But google links are accessible from all, I need to add some restrictions as file can be viewed only by their owner.
I know it's a major task, but i just need some sort of logic. Please share your thoughts.
Thanks.
Any cloud storage service can be used for this. You'll get HDD space. There is not storage server who provides revision control system for this. You can use git, svn for this though. But as the files are binary you can not get full facility of these tools.
How file will be previewed depends on you. If you use PHP you make the site and at the backend you use the API to interact with the storage service. Google doc is not an option for this if you use PHP. Also note Google links can be made private.
I suggest you this,
Find a cloud storage service and use the storage in your server. Any will do.
Create UI using PHP and control the access using PHP too.
Manipulate files in your server directly or in 3rd party storage server via API
Use a revision control system to track the changes. And use its API in PHP end.
Some cloud storage service
Amazon S3. It also supports Versioning.
Google Cloud Storage
Microsoft Azure
Try Microsoft SkyDrive or Google Drive or Dropbox
